Ocular disease and low vision care anchor the San Diego practice of Rossanna V. Alo, OD, an optometrist in Allied Gardens who holds California optometry license OPT10948T and practices at 4647 Zion Avenue on the Kaiser Permanente Zion Medical Center campus. The same Zion Avenue medical corridor houses Allied Gardens Family Optometry for primary vision care outside the Kaiser network, and both practices serve the 92120 ZIP's dense residential population along Waring Road and Greenbrier Avenue. Alo earned her Doctor of Optometry degree from Southern California College of Optometry in 1997 and completed a residency focused on ocular disease and low vision rehabilitation before joining the Southern California Permanente Medical Group. Her clinical scope includes diagnosing refractive errors, pterygium, pinguecula, and systemic conditions that manifest in the eye, such as diabetic retinopathy and hypertensive retinal changes. The residency training in low vision means she fits magnification devices, prismatic lenses, and adaptive optics for patients with macular degeneration or other conditions that standard corrective lenses cannot fully address. Her work within Kaiser's integrated model connects optometric findings to internal medicine records, allowing physicians to act on ocular indicators of systemic disease across departments. Patients with complex prescriptions requiring compounded ophthalmic preparations fill them through Alvarado Compounding & Retail Pharmacy on nearby Alvarado Road. The Zion campus is a 271-bed facility that integrates optometry, ophthalmology, and internal medicine referrals under one roof.
